Cool tool! It's amazing to see BGP in action and what 'really' happens. A
comment: could you define the number of prefixes a little more? E.g., is it
the total imported and exported across the link, imported only, exported
only, context dependent, etc.

The animations are in SVG (a W3C graphics standard) and should be
viewable in any web browser but you'll probably have to download an SVG
plugin first (there's a link to Adobe's free plugin at the top of the
web page).

If you play with the stuff, we'd welcome coments, suggestions, whatever.
Thanks.
